Graphics Preferences

In the Main Menu, click File, Graphics.

This window is obsolete!

You should never need to go into this window unless you are using an unsupported version of Windows. (See Computer Requirements.) The entire lower half is for technology from 15 years ago. The upper half is for DirectX 11 which has been included with Windows since Windows 8.0. Everyone should use DirectX 11, but this window does give you the option to use the older DirectX 9 or OpenGL if you really need to. This might be done for increasingly rare troubleshooting, to compare the 3D Toothchart drawing for older versions versus newer versions.

If you use an older graphics option, certain features will not be available:

Graphic settings affect the display of the Graphical Tooth Chart, the Graphical Perio Chart, and the graphics displayed on printed Treatment Plans.

Users must have the Graphics Edit permission to access and change graphic settings.

DirectX 11 Tooth Chart on all computers: This section affects all workstations connected to the database.

DirectX 11 Tooth Chart: This section affects this computer only.

DirectX 11 status on this computer: Lists the current status of DirectX 11 on this workstation. Setting is updated automatically once the Chart Module has been viewed and cannot be changed.

Older Tooth Chart Technology: Select the tooth chart to use when DirectX 11 is not available.

Options for Older Technology: These options are only available when DirectX 11 is not available and older technology is being used.



Crash on startup (with Event Viewer error referring to Direct2DWrapper), or missing Module Buttons, or unacceptable 5% background CPU usage:
Update Open Dental to latest stable. You have the option of turning off DirectX (Direct2D) for the general icons. The only downside is that the icons will be a little fuzzy when using zoom. This is done one computer (or app server) at a time. Go to C:\Program Files (x86)\Open Dental\. Manually add an empty text file called "NoD2D.txt". If your computer does not show file extensions, then it will just look like "NoD2D". Now, when you start Open Dental, it will not use Direct2D.

Note: This should not be confused with the other similar file called NoDpi.txt, which is discussed in Zoom

If the old DirectX 9 tooth chart is still not working properly (and you cannot use DirectX 11 for some reason):

If you cannot get into Graphic Preferences on your computer you can change the graphic setting from a different computer to use Simple Graphics. See Computers.

Technical Details


DirectX is not available for Open Dental Cloud users. Instead, Open Dental Cloud users will automatically use OpenGL.
